FSANZ approves new antimicrobial processing aid for meat and poultry

Food safety authorities in Australasia have approved
dibromo-dimethylhydantoin (DBDMH) as a processing aid to treat all foods.

Food Standards Australia New Zealand
(FSANZ) said DBDMH had been given the go-ahead to be used as an antimicrobial
washing agent across the board – although its main uses were likely to treat
meat and poultry, as well as water in ice-making systems for use in poultry
processing.

The approval came following an application
by Elanco Animal Health to amend Standard 1.3.3 – Processing Aids, of the Australia
New Zealand Food Standards Code FSANZ confirmed it had carried out the
appropriate assessment and found the substance was fit for purpose – or

“technically justified” - and posed
no public health risks.

Joint entry request rejected

When added to water, DBDMH hydrolyses to
form hypobromous acid - an active compound that possesses antimicrobial
activity. Hypobromous acid kills bacteria present on the surface of food such
as E.coli 0157:H7 and Salmonella, said the food safety watchdog.

It noted that the regulations currently
allow for use of a similar antimicrobial halohydantoin agent called
bromochloro- dimethylhydantoin (BCDMH) for the treatment of all foods.

Elanco asked that the entry for BCDMH be
replaced with a joint entry for DBDMH and BCDMH in the part of the Code
relating to permitted bleaching, washing and peeling agents.

However, FSANZ has proposed including
DBDMH as a separate entry to clearly distinguish the different residues from
each chemical and their levels.

This permission would include maximum
permitted levels (MPLs) of 2.0 mg/kg for dimethylhydantoin (DMH) and 2.0 mg/kg
for inorganic bromide in the treated food. The MPL for inorganic bromide from
the new chemical differs to the maximum amount of 1.0 mg/kg of inorganic
bromide, said the body.
